Integrate banking features into invoicing and other apps
Online credit card clearing
For use in POS during an online purchase
Social Media
Integrate social media into admin areas of CMS's. Eg: post to FaceBook and Instagram as you post to your blog

Current system outdated. Needs completely overhauling
